PowerPoint to PDF, free and clean
Drop a .pptx, get a PDF. Free, no watermark, one page per slide.
Three steps, done
Drop your PPTX
Drag a .pptx onto the page or pick one. Up to 50 MB.
Slides render at high resolution
Every slide is drawn at twice its size — text, shapes, charts, images, gradients.
PDF downloads automatically
A single PDF lands in your downloads folder. Slide size is preserved — 16:9 stays 16:9, 4:3 stays 4:3.
Your deck, with a voice
Narrated PowerPoint
Every slide voiced by an AI voice, timed to auto-advance. Download the .pptx and press play.

Before
Your .pptx deck
Any PowerPoint 2007+ file up to 50 MB. No PowerPoint install, no account needed — works on phones too.
After
One PDF per deck
High-resolution slides in the original aspect ratio, one page per slide. No watermark, free and unlimited.
Want it narrated instead of printed?
A PDF is for reading. If the deck needs to be heard, tell Noty in the Studio chat — it writes the narration from your slides and notes, voices every slide, and hands back a PowerPoint that plays itself.
Why convert PPTX to PDF?
PDFs render the same on every device, can’t be edited by accident, and don’t need PowerPoint to open. That’s why most decks end their life as a PDF.
Email-friendly handouts
A PDF opens on any client, on any device. No "I don’t have PowerPoint" replies, no formatting drift.
Printer-ready
Most printers prefer PDF over PPTX. Margins behave, fonts embed, slides print one-per-page or as a handout.
Client deliverables
Ship the final deck as a PDF so it can’t be edited. The version you sent stays the version they see.
Lecture archives
Students keep notes for years. PDFs survive software changes — a 2010 PDF still opens; a 2010 .pptx sometimes doesn’t.
Web sharing
Drop the PDF into Google Drive, Dropbox, or any link-share service and viewers see it inline — no app install.
Archival format
PDFs are the closest thing to a long-term format for documents. Use them for anything you might want to read in 5 years.
What you can get from one deck
Any converter can make a PDF. The difference is what else the deck can become — a narrated PowerPoint, an MP3, a whole new deck from a brief.

Use the free converter above for the PDF. When the deck needs to be heard, tell Noty — it narrates every slide and hands back the .pptx and the MP3.
What the PDF looks like (and what it can’t do)
Every slide is rendered as a high-resolution image inside a PDF page. That’s great for fidelity and matches what your audience sees in PowerPoint.
The strengths: pixel-accurate slide layout; charts, SmartArt and gradients preserved; the original aspect ratio kept; no watermark and no branding; slides rendered at twice their size, so they stay sharp on screen and in print.
The honest tradeoffs: slides are images, so the text inside isn’t selectable. Slide animations and transitions become static. Embedded video and audio aren’t included. EMF/WMF corporate icons may simplify.
Need a text-searchable PDF? Open the deck in PowerPoint and use File → Export → PDF. The browser converter is built for fast, no-install conversion — not for text indexing.
Converting large decks
Big decks render slide-by-slide so your browser doesn’t freeze. Progress shows under the file header — you can watch each slide tick over.
A 50-slide deck takes about 30–60 seconds depending on slide complexity. Output PDFs are usually 2–10 MB for a 30-slide deck.
Make the deck speak
Noty narrates every slide in a natural voice — or yours — and hands back a PowerPoint that plays itself, plus the MP3.

Frequently Asked Questions
How do I convert PPTX to PDF for free?
Drop your .pptx file into the converter above. Every slide becomes a PDF page, then the file downloads automatically. No watermark, no install.
Is there a watermark?
No. The PDF has your slides and nothing else — no watermark, no branding.
Are my files uploaded?
No, the PDF is built in your browser.
Is the PDF text-selectable?
No, each slide is embedded as a high-resolution image. If you need selectable, searchable text, open in PowerPoint and use File → Export → PDF.
What’s the file size limit?
Input is capped at 50 MB. Output PDFs vary based on slide complexity — usually 2–10 MB for a 30-slide deck.
Does it support .ppt (older format)?
Only .pptx (PowerPoint 2007 and later). Open older .ppt files in PowerPoint, Keynote, or Google Slides and save as .pptx first.
Do animations and transitions work in the PDF?
No. PDFs are static — animations, transitions, and embedded video aren’t preserved. The visible state of each slide is captured.
Why is conversion slower for large decks?
Each slide is rendered individually so your browser stays responsive. A 50-slide deck takes about 30–60 seconds depending on slide complexity.
Can I convert multiple files at once?
Not in this tool — convert one deck at a time. Once a PDF is ready you can download it again, then pick “New file” to convert the next deck.
Is the output PDF/A compliant?
No. Use Adobe Acrobat or PowerPoint’s export options if you specifically need PDF/A for archival compliance.
Can Notevibes narrate the deck instead?
Yes. Tell Noty in the Notevibes Studio and it voices every slide from its text or speaker notes, then hands back a narrated .pptx that auto-advances and an MP3 of the whole deck. Pick a natural AI voice or clone your own. Video export is coming with the next update.
